Fractional-Pixel CO₂ Laser Treatment in Patients With Urodynamic Stress Urinary Incontinence: 1-Year Follow-Up

Area of Science:

• Gynecology
• Urology
• Medical Technology

Background:

• Vaginal fractional pixelated low power and long pulses (LPLP) CO2 laser is an emerging treatment for stress urinary incontinence (SUI).
• Previous studies indicated short-term benefits, necessitating longer-term efficacy evaluation.

Purpose of the Study:

• To evaluate the 1-year subjective and objective efficacy of vaginal CO2 laser treatment in women diagnosed with urodynamic SUI.
• To assess the durability of treatment effects over a 12-month period.

Main Methods:

• Prospective, multicenter study involving patients with mild to moderate urodynamic SUI.
• Three sessions of fractional pixelated CO2 laser therapy administered vaginally.
• Follow-up assessments at 6 and 12 months included 1-hour pad tests, validated questionnaires (PFDI-20, PFIQ, PGI-I), and urinary diaries.
• Urodynamic re-assessment at 6 months.

Main Results:

• Significant reduction in 1-hour pad test weight from baseline (6.3g) to 12 months (3.7g, P<0.05).
• High patient-reported improvement (PGI-I) at 12 months (64.3%).
• Sustained significant improvements in PFDI-20 and PFIQ scores throughout the 12-month follow-up.
• 41.4% of patients achieved resolution of stress incontinence based on 6-month urodynamic assessment.

Conclusions:

• Vaginal CO2 laser therapy demonstrates significant efficacy for mild-to-moderate SUI over a 1-year period.
• Treatment benefits are supported by both objective and subjective outcome measures.
• The procedure appears safe, with no serious adverse events recorded.
